Traffic Advisory

January 28, 2022 - Southeastern Colorado - Work continues on I-25 Rehab and Charter Oak Ranch Road Projects

COLORADO SPRINGS — For the week of January 30 there will be nighttime left lane closures on northbound I-25 (between Mile Post 131 and 135). This is necessary to allow crews to set temporary concrete barrier and restripe lanes in preparation to move traffic eight feet to the outside.

Earthwork continues east- and westbound on Santa Fe Avenue and Charter Oak Ranch Road. In addition, there will be a full road closure at the intersection of Santa Fe Avenue and Charter Oak Ranch Road Tuesday, Feb. 1 and Wed. Feb. 2, between 7 a.m. and 5:30 p.m., to allow work on the waterline crossing. A detour will be in place.

Commuters will continue to experience a lane shift on northbound I-25 beginning at MP 128 and continuing to MP 135. Crews have been constructing stream diversions at Dry Wash (MP 128.34) and Clover Ditch (MP 131.2), saw cutting the bridge decks, removing the bridge guardrail and bridge overhangs. Commuters will experience narrowing of lanes on I-25, please eliminate distractions so you and your passengers arrive safely to your destination.

Motorists are encouraged to register for text alerts by Texting MAMSIP to 888-970-9665

A Courtesy Patrol will be driving the work zone and will respond to incidents when notified. Hours of operation are 7 a.m. to 6 p.m., Monday through Friday and holidays.

Project Overview

Interstate-25 – Safety and efficiency improvements

  • The improvements to I-25 addressed in this project are located along an approximately 7.5-mile segment of the corridor beginning at South Academy Boulevard and extending to the Santa Fe Avenue (CO 85/87) exit at Fountain (MP 128), which exits to Gate 19 of Fort Carson.
  • Replacement of two bridges crossing over South Academy Boulevard;
  • Widening of both inside and outside shoulders and installing safety improvements; 
    Concrete surface treatment overlay to provide an improved riding surface for this 7.5-mile segment;
  • Installation of median barrier the entire length of this corridor; 
  • Rehab and widening work on four bridges along the corridor, and 
  • Installation of I-25 Southbound deceleration lane at the interchange with Colorado Highway 16.

Safety Benefits

The safety enhancements relate to the potential to reduce crashes, improve infrastructure, and address physical deficiencies that contribute to crashes in the corridor. CDOT conducted a safety assessment for the corridor to evaluate the magnitude and nature of safety problems and analyze the causes of crashes.

The proposed transportation improvements are mitigation measures to reduce crashes and improve safety in the corridor. It is estimated that the delivery of the MAMSIP project will, over its’ twenty years of operation, result in fewer deaths, injuries, and crashes on the four corridors the project addresses.
